Android Open source Framework (ii) Introduction of okhttp-utils based on okhttp further encapsulation

Okhttp-utils is Zhang Hongyang is a framework library based on the Okhttp package. The actual work, not much use, for small projects of network requests and file transfer can be considered for direct use. Otherwise, it is based on the mainstream Okhttp+retrift+rxjava framework.

For okhttp use, you can do some encapsulation according to your own project needs. If you are dealing with a temporary project at hand, you can draw on GitHub for some open source Okhttp package libraries. Just go to GitHub and search under Okhttp will come out many packaged frames.

Analysis Okhttp-utils use, just for your own learning to understand.

I. Introducing Okhttp-utils as module into the project

　　　　

Two. Okhttp-utils introduced into the project file list directory:

　　　　　　　　

Three. Okhttp-utils basic use 1. GET Request data

okhttputils        . Get ()        . URL (URL).        ID (+).        build ()        . Execute (new Mystringcallback ());

2.//post Request Data

okhttputils.        poststring ()        . URL (URL)        . MediaType (Mediatype.parse ("application/ Json Charset=utf-8")        . Content (new Gson (). ToJson (new User (" Zhy " " 123 " ))         . Build ()        . Execute (new mystringcallback ());        

3.//Uploading Files

okhttputils        . Postfile ()        . URL (url).        file (file)        . Build ()        . Execute (new Mystringcallback ());

4.//Loading Pictures

okhttputils.Get(). URL (url). Tag ( This). Build (). Conntimeout (20000). ReadTimeout (20000). WriteTimeout (20000). Execute (NewBitmapcallback () {@Override Public voidOnError (call call, Exception E,intID) {Mtv.settext ("OnError:"+e.getmessage ()); } @Override Public voidOnresponse (Bitmap Bitmap,intID) {LOG.E ("TAG","Onresponse:complete");            Mimageview.setimagebitmap (bitmap);    }        }); 

5.//uploading a single file

Okhttputils.post ()//        . AddFile ("mfile""messenger_01.png  ", file)        . URL (url)         . params (params) // with form data         . Headers (headers)        . Build ()        . Execute (new mystringcallback ());    

6.//Uploading multiple files

 okhttputils.post (). AddFile (  " mfile   ", "  Span style= "COLOR: #800000" >messenger_01.png   "   " mfile  " ,  " test1.txt  "  , file2). URL (URL) . params  (params ) //   Build (). Execute ( new  mystringcallb    ACK ()); 

7.//Download File

okhttputils.Get(). URL (URL). Build (). Execute (NewFilecallback (Environment.getexternalstoragedirectory (). GetAbsolutePath (),"Gson-2.2.1.jar") {@Override Public voidOnbefore (Request request,intID) {} @Override Public voidInProgress (floatProgressLongTotalintID) {//Progress bar DisplayMprogressbar.setprogress ((int) ( -*progress)); LOG.E (TAG,"inProgress:"+ (int) ( -*progress)); } @Override Public voidOnError (call call, Exception E,intID) {LOG.E (TAG,"OnError:"+e.getmessage ()); } @Override Public voidOnresponse (File file,intID) {LOG.E (TAG,"Onresponse:"+File.getabsolutepath ());    }        }); 

The public callback method defined:

 Public classMystringcallback extends Stringcallback {@Override Public voidOnbefore (Request request,intID) {} @Override Public voidOnafter (intID) {} @Override Public voidOnError (call call, Exception E,intID) {e.printstacktrace (); } @Override Public voidOnresponse (String response,intID) {LOG.E (TAG,"Onresponse:complete"); Mtv.settext ("Onresponse:"+response); Switch(ID) { Case  -: Toast.maketext (mainactivity. This,"http", Toast.length_short). Show ();  Break;  Case 101: Toast.maketext (mainactivity. This,"HTTPS", Toast.length_short). Show ();  Break; }} @Override Public voidInProgress (floatProgressLongTotalintID) {LOG.E (TAG,"inProgress:"+progress); Mprogressbar.setprogress ((int) ( -*progress)); }    }
